Follow these 8 expert tips to maintain your microwave and extend its lifespan, whether it’s an over-the-range or countertop model.

1. Clean Spills Quickly

• Why: Leftover food can absorb microwave energy, causing hot spots and potential damage.
• How:
• Wipe spills immediately with a hot, damp cloth.
• Wash removable parts like the turntable in hot water with dish soap.
• Remove odors by microwaving a bowl with ¼ cup of lemon juice in water for 1 minute.
• Scrape stubborn stains gently with a plastic card.

2. Use the Exhaust Fan

• Why: Steam from cooking can damage the microwave’s electronics.
• How:
• Always turn on the fan when cooking below your microwave.
• Wipe off collected moisture with a paper towel or cloth.

3. Degrease the Grease Filter

• Why: Clogged filters reduce efficiency and pose a fire hazard.
• How:
• Slide out the filter and soak it in hot water with a degreasing detergent (e.g., Dawn).
• Check the manual for dishwasher compatibility. Replace filters if they don’t fit snugly.

4. Handle the Door Gently

• Why: Slamming the door can damage safety interlock switches that are essential for operation.
• How:
• Close the door carefully to ensure switches and latches align properly.

5. Avoid Running It Empty

• Why: Without food, microwaves can overheat and cause interior damage.
• Tip: Double-check that food is inside before starting the microwave.

6. Steer Clear of Metals

• Why: Metal can cause arcing (sparks) that damage the microwave cavity.
• How:
• Avoid metal utensils, dishes with metallic trim, and twist ties.
• Use aluminum foil only if tightly wrapped around food, with clearance from the microwave walls. Check your manual for specifics.

7. Use Preset Cooking Times

• Why: Prevent overcooking, spattering, or overheating.
• How:
• Take advantage of preprogrammed settings for common items.
• Double-check cooking times before starting. Example: Avoid entering 50:00 instead of 5:00.

8. Leave Repairs to the Pros

• Why: Microwaves contain capacitors that hold high-voltage charges even when unplugged, posing a severe electrocution risk.
• How:
• Get professional repairs for electronic issues.
• Always request an estimate; replacing might be more cost-effective than repairing.

Bonus Tips for Longevity

• Inspect Regularly: Check seals, latches, and vents for signs of wear or buildup.
• Maintain Consistency: Keep usage regular and avoid pushing the appliance to its limits.

By following these simple practices, you can ensure your microwave remains efficient, safe, and long-lasting.
